To' all 'whom' t'may concern Be it known that I, CHARLES W. RENNER,acitizen of the United. States, residing. at Altoona, in the countyotBlair and State of Pennsylvania, have inventedcertain new and usefulImprovements'in Gar-Roof Construction, of whichjthe following is aspecifica- Thisinve'n-tion relates to the subject of car roofs, andparticularly to a type of roothat maybe advantageously used in theconst-ruction of frei ht cars, although not at all necessarily limitedto this class of railway rolling l stock. f

Many ot the roots now in use, employ wooden construction, together withiron or steel frame' work. In this method the wooden lparts are apt toquickly .rot away-f and, ocourse, render the root of short service.Therefore, the present methods involve considerable' expense for theirmaintenance and repair. Accordingly, the genera-l object of the presentinvention is to provide a simple, practical, andv durable roofconstruction that on cars ofthe all-steel type that are now coming intogeneral use. The structure* set forth in this case is made entirely ofmade that' any and all quickly replaced and easily repaired- T hedurability oit' metal, of course, being' greaterthan that ofl wood,.makes the cost of maintenance in general much lower thanotherwise wouldbe the case where'wood,

are employed.

f Another object ot this invention is to provide aA construction whereinthe roof sheets, that Aare used inconnection therewith, eX- tendfrom oneside of'. the car tothe other.

This-.does away with the necessity of having a joint atthe center of thecar, which is con'- ftinu'a'lly needing attention where it exists 1nactualfiiise.l It will also-he obseryedfwith refe're'nceto theroofsheets lextending from one side of the car to the other, that thesame, when' properly locked in the roof trames. greatly strengthens' theentire car and increases the stability thereof.

A u'rtherobject of the invention is to pro-- vide channeledmetalcarline's, th'at are pro-4 vided with' means tor connecting eachother through the medium of a metal pui-lin, and are-adapted to receivethe inturned edges of `the roof sheets in their channeled portions. Inord er to lock the sheets within the carline iron'or steel, and is soparts thereof may beor wood parts there is employed a removable lockingbar that is adapt-ed to slide in the channels of the carlines, and whensecured therein the said bar holds the root' sheets in the carline.

A still yfr'u'rther object ofthe present i'nvention'is to provide ametal roof Jframe construction that will permit the use of bridge blocksJfor supporting the running board, in such a manner that the interior ofthe car is at all times protected against a leak. occurlring at thisparticular point.

- Vit-h these and many other objects in view, which will more readilyappear to those skilled in the art as'the description-'0f the caseproceeds, the same consists in the novel construction, combination andarrangement of parts hereinafter more. 'fully described,'

illustrated `and claimed.

A preferred and'practical embodiment of the invention is shown in theaccompanying drawings, in'4 'which- Figure 1 isa perspectiveview,.partly in section, of a portion of a car havingthe improved rooconstruction. Fig. 2 is a vertical sectional view of-one of thecarlines. Fig. 3 is a cross sectional view of a carline and a bridgeblock supporting the running fboard. Fig. d is a vicw similar to Fig. 3showing modification. Fig. 5 is a detail cross sectionalview of one oi'the carlines showing a modified form of channel and locking bar. Fig. 6is a perspective View of a channeled metal carline. Figs. 7 and 8 aredetailed cross sectional views of a carline showing different forms ofchannels. Fig. 9 is a perspective view of the locking bar employed 'inconnection with the carline. Figs.` 10 and 11 are detailed views of alocking bar, Fig. 10 showing a cross section, and' Fig. 11 the endthereof,k that terminates at the center ofthe car. Fig. 12 is aperspective view of a bridge-block. Figs. 13 and 1 4 are detailsectional views of bridge blocks. Fig. 15 isa longitudinal sectionalView of a pressed steel carline. Fig. 16 is 'a detail cross sectionalView on the line w-y of Fig.-

letter C designates .a car body, which may be either of woojd or steel,and the letter F designates the frame work around the top of the carbody.

The reference numerall 1 refers to a channeledmetal carline, which maybe made of iron or pressed steelwhichever is preferred. The 'channeledportion of the carline, which is designated as 2, extends the fulllengthv vof the carline,

and the sides of said channeled portion preferably converge upwardly. Itwillof course be understood that the carline 1 extends from one side ofthe'car body to the other, that is, it spans the car bodyfro'm one sideto the other, and engages the said frame with they saddle portionsThese'saddle portions are provided with holes t to permit the ends ofthe carline to be securely bolted to the ear frame. The said carline 1is also provided along each side thereof with a plurality of perforatedfastening ears 5. ing ears 5, are designed to support the metal purlins6, the latter also being secured to the said ears 5. This constructionunites 1 one carline With another, and alsov provides a support for theroof sheets 7 which are designed to span the portion between eachcarline. The said vroof sheets 7 are undivided, that is they extend fromone side of the car body to the other, and the edges thereof 4are turneddownwardly as indicated at 8. The said inturned edges 8 of the roofsheets 7 are adapted to enter t-he channeled `portions 2 of the carline,thereby causing the roof sheet to conform with the line of curvature ofthe carline,4 and also, to a degree serve to hold the roof sheets inplace.

In order to positively and securely hold the roof sheets in'place, andlock thesame within the channeled portions of the carline, there isprovided a locking bar v9, which is of substantially T-shape in crosssection. This locking bar is provided with a locking tongue 10 which isof the sameshape as the channel in the carline. It will also. beobserved that the said locking bars 9 terminate near the central portionofthe carline, and have at theirinner or terminal ends a socket member11. The construction of the said locking bar permits the same to be slidin the channel port-ion of the carline after the edges of theroof sheetsare placed within the channel portion 2, thus locking the roof sheet inthe carline. The outer end of the locking bar is provided With a hole12l which is adaptedto receive a suitable fastening which `will alsoenter Vthe hole 4a on the outer en d of the carline. This .fasteningwill, of course, prevent the locking bar from sliding out of the`channel of the carline.

From Fig. k5 it will be observed that the channeled portion 2a of thecarline 1 has vertical sides, and that the edges 8 of the roof sheet 7are locked therein by the locking bar 9 which has a tongue 10aL whosesides are also vertical. This construction will permit of the lockingbar being pushed down into the carline and thereby lock the The saidfasteni jection 20 bythe bolt 20,

roof sheets in place, instead .of sliding the locking bar into place asisshown in the otherinstances. As has been pointed out before, it willbe evident that two locking bars are required to lock the roof sheets ineach carline, and that the said locking bars meet -at the center of theroof. At this point there -is placed a bridge block 13 which is providedwith the down turned flanges 14 that are adapted to engage over thesides o f the locking bars at their meeting portion. The underside ofthe bridge blocks-13'is provided with downwardly projecting studs 15which are adapted to enter the sockets 16 in the top of the locking bar.These studs 15 when in the sockets 16 serve`to hold the locking bars 9together at their inner parts, in addition to the fasteningsat theirouter ends which enter thecar frame. The bridge block 13 is furtherprovided with a central fastening receiving hole 17, and bolt holes 13*1in the top portion thereof to receive fastening bolts from the runningboard 18. A bolt 19 is employed for holding the bridge block 13 to theearline 9, the said b olt also serving to irmly hold, by pressure uponthe bridge block, all of the parts at the center of the carline, firmlyin place. i

The modiiied form of carline shown in Fig. 8, and also in Fig. 4,employs for locking the bridgeblock 13 to the carline, a T head bolt 19,the T portion of saidbolt engaging the shouldered portion 2 0 of thecarline 1, and thereby rmly holdlng t-he parts at the center of thecarline firmly together as in the other instance. In connection with thefastening members 19 and 19 it` will be observed that they' aresurrounded Aby the sockets 11 formed in thek meeting ends of thelockingbars to come flu-sh together and thereby make a tight jointattheir meeting ends. The construction illustrated in Figs. 1 to 12inclusive shows the application of the in; vention when iron frame worklis used, While Figs. 13 to 15'inclusive show the invention used withpressed steel. In this connection, it will be observed that theconstruction of the channeled carline is substantially the same as. thatof the one shown in Fig. except that its outer'portion, instead of beingprovided with a saddle, is provided with the perforated 'projectingportion 20, and the perforated angled portion 21 which is adapted to besecured `to Vthe car frame. The same typeof locking bar 9 is elnployedwith the pressed steel carline, and' is fas-v tened at its outer end tothe perforated prosteelform of carline at the center thereof is Weldedan upstanding sleeve. 22 which is In the pressed l adapted to receivethe fastening bolt 19b which is adapted to secure the bridge block 13 tothe parts at the center of the carline, The Welding of this sleeve tothe carline makes an absolutely ltight and Water proof connectionbetween the elements at .the center of the roof, and thereby preventsthe water from entering the interior of the car.

, From the foregoing description, it, is believed that it will bereadily apparent that the looking bars. 9 can be easily removed orv asto 'effect the removal of the and that the bridge blocks can replaced soroof sheets,

also be rem-oved for repairing or replacing' r water from beating upunder the Vlocking bar, and also gives 'the ends of the car a finishedappearance. v
